Have you tried playing the music on that fabric? I had some similar (but not quite the same) when I did my first ever wall hanging (at the class that taught me all the fundamentals and got me hooked on quilting) and my husband played it on the piano and identified it as Rachmaninoff!

Wow. That is really interesting. I am in no way musical. My talents if I have any lean towards the quilting/sewing ability. Got that fabric in a bundle of fat quarters I bought off Ebay. lol
